Abstract: PURPOSE: A circuit for generating a pulse word line is provided to prevent the decrease of a pulse width by compensating for the decrease of the pulse width through combination of reference voltage and a delay circuit. CONSTITUTION: When a logic combination is performing by using a signal(Nd6), an output signal(Nd17), and an output signal(Nd16), the output signal(Nd16) of the 7th NAND gate(NA7) is high regardless of a signal going through the 17th node(Nd17) and the third delay circuit part(50) because a reference voltage is low. A pulse width of the 8th NAND gate(NA8) is operated through a signal combination of the 6th node(Nd6) and the 17th node(Nd17). If a source is high voltage, the reference is high, and a pulse(pwlt2) is generated according to a combination signal with the output signal(Nd17) and the output signal of the third delay circuit part(50). At this time, because the pulse(pwlt2) is generated by going through the 8th NAND gate(NA8), a width of an output pulse signal is compensated as much as the third delay circuit part(50).
